If you're in northwest Arkansas (Fayetteville, Springdale, Rogers, Bentonville), there is a truck stop at Exit 58 (Greenland, AR) on Interstate 540. The road in front on the truck stop is West Wilson.
Head east on West Wilson, through Greenland, for about 1 mile. You will come to the intersection of West Wilson and U.S. Highway 71. Take a right on U.S. 71 and head south. From Greenland it's about 10 or 11 miles south to Brentwood where there is a rest area. About 5 or 6 miles south of Brentwood is Winslow. The road will get steep there and go over Mt. Gaylor.
U.S. 71 is a great road for cycling. At West Fork, south of Greenland, the road goes from 4 lane (no shoulder) to 2 lane with a good shoulder. Not much traffic on 71, as most of it is on I-540 now.
